A bad coolant temp sensor can cause a code P0711 but not a tps code. What is the exact code number you have not code descriptions? Also can your scan tool read live data like the tips sensor?

It can cause high idle and hard shifting it could be the wires I really doubt its the sensor itself.I have seen very few go bad in all the years I have worked for Saturn.

The tips miss reading can cause a high idle the best way to diagnosed it is get a scan tool that can read live data like tps etc There like 50 or so on amazon. Or take it to a shop to diagnose. Your going to need tools like a multi meter scan tool that can read live data etc to diagnose it.
